Adjustments on Perpetual Swap Price Limits for ETH, EOS, And Other Currencies

Dear valued customers,

Due to recent volatility in ETH, EOS, LTC and other currencies, we will adjust the Perpetual Swap price limits as follows:

BTC

First 10 minutes of all newly listed contracts:

• Upper Limit = Spot Index Price x (1 + 0.5%)
• Lower Limit = Spot Index price x (1 - 0.5%)

After 10 minutes:

• Upper Limit = Average Basis within last 10min + Spot Index Price x (1 + 1%)
• Lower Limit = Average Basis within last 10min + Spot Index Price x (1 - 1%)
• Basis = Contract Price - Spot Price

If the price limit deviates from the Spot Index Price by 2% or is below 0:

• Upper Limit = Spot Index Price x (1 + 2%)
• Lower Limit = Spot Index Price x (1 - 2%)

Open long or close short position:

• An order would be blocked if the order price sent is higher than the price limit.

Open short or close long position:

• An order would be blocked if the order price sent is lower than the price limit.
